Victor David Hanson has a great piece:

Do they think it a bad thing that Noriega, Milosevic and the Taleban are gone? Whatever the endemic cynicism over US aims, the "national liberation" mantra of the 1960s seems close to realisation, if the nascent democratic movements in Panama, Serbia, Afghanistan and Iraq are any indication. The demonstrators should at least harbour no sympathy for our enemy's agenda: the fundamentalists' treatment of women, homosexuals, religious dissidents and ethnic minorities is from the Dark Ages.

Are the protesters repulsed at a "new" American preemption? If so, we in America do not remember that Hitler first sent V2s to our shores or that Milosevic cleansed Americans before we sent planes over their skies to stop the butchery. In the recent Balkan conflict Americans thought European omission, not American commission, allowed the loss of 250,000 lives a few hours from Berlin and Paris.

Mr Bush's Christianity, cowboy metaphors, and drawl might grate on European sensitivities. But he sought approval of the US Senate and went to the UN before attacking Saddam, unlike a lip-biting Bill Clinton, who bombed the Balkans, Africa and Iraq without either national or multinational sanction. And, by the terrible arithmetic of war, the Anglo-American effort to defeat the worst regime in the Middle East has been remarkable in its efforts to minimise casualties, both ours and Iraqi.

As they say, read the whole thing.
